One Minute Mentor: Transformation behavior of Austenite

The transformation behavior of retained austenite in M2 steel was examined under varying tempering conditions. The steel was initially subjected to interrupted quenching at 105 °C (225 °F), a process that elevated the retained austenite content to approximately 55 vol %, compared to the typical 25 vol % observed after direct quenching to room temperature. This was followed by tempering at 565 °C (1050 °F), without intermediate cooling. Results indicated that double tempering was significantly more effective than single tempering at transforming retained austenite under these conditions. Furthermore, repeated tempering cycles accelerated the complete transformation of retained austenite, achieving full conversion in a shorter total processing time than single-stage tempering.

One Minute Mentor: Effects of cyclic treatments on martempered L3 steel

The effects of various subcooling and tempering cycles on martempered L3 steel were investigated with changes in specimen length tracked throughout the treatments. All length changes were measured relative to the original, as-martempered state.

The study included four treatment protocols, each maintaining a total tempering time of 10 hours at 120 °C (250 °F), though distributed differently across cycles:

  • Treatment A: Specimens were cooled to −195 °C (−320 °F), then cycled ten times between 20 and 120 °C (68 and 250 °F), holding for 1 hour at 120 °C in each cycle.
  • Treatment B: Samples were tempered for 1 hour at 120 °C, then cooled to −195 °C and held for 1 hour. This sequence was repeated for a total of ten cycles.
  • Treatment C: Specimens were first cooled to −195 °C and held for 1 hour, then tempered at 120 °C for 1 hour. This subcooling-tempering sequence was also repeated ten times.
  • Treatment D: Specimens were cooled to −195 °C and then tempered continuously for 10 hours at 120 °C.

For clarity, the length changes from Treatment D were omitted from the associated figure (Fig. 3), though its net expansion was found to be comparable to that of Treatment A.

Results indicated that the first two refrigeration cycles following martempering were effective in reducing retained austenite in L2 and L3 steels. However, additional cycles beyond the initial two offered no significant benefit. Regardless of cycle structure, maintaining a cumulative tempering time of 10 hours at 120 °C appeared to be a critical factor for dimensional stability.

Two particularly effective strategies combining tempering and subcooling were highlighted:

  • Temper for 1 hour at 120 °C, subcool, repeat the cycle, then temper continuously for an additional 8 hours.
  • Subcool, temper for 1 hour at 120 °C, subcool again, then temper continuously for 9 hours.

These approaches suggest that combining initial subcooling with sufficient cumulative tempering can effectively stabilize the microstructure and dimensions of martempered L3 steel.

Platinum deficit predicted for third year as palladium returns to balance, Johnson Matthey reports

Johnson Matthey, London, England announced that the platinum market will remain in deficit in 2025 while palladium moves back into balance, according to its 2025 PGM Market Report released ahead of London Platinum & Palladium Market week. The company forecasts a 3% decline in primary platinum output due to operational restructuring, extreme weather and maintenance in South Africa, with secondary supplies subdued globally except in China, where a renewed trade-in incentive scheme is boosting scrap returns. Industrial platinum demand is expected to grow modestly, driven by capacity expansions in chemicals, fibreglass, biofuels and synthetic fuels, even as automotive use declines 5% amid the shift to battery electric powertrains.

Palladium, which faced structural deficits from 2012 to 2024, should reach equilibrium in 2025 as stronger recycling in China offsets reduced primary output from South Africa and the U.S., despite weaker scrap flows elsewhere, and a 5% drop in automotive palladium use.

The rhodium market is forecast to stay in deficit after South African supply falls and auto consumption dips, while industrial demand rebounds with normalized glass-industry purchasing. Ruthenium demand is set to climb 2% on data-centre expansions and robust chemical catalyst use, likely resulting in a significant shortfall without further inventory drawdowns. A slight rise in iridium production should help balance that market, as lower chemical usage is offset by increased crucible demand.

Rupen Raithatha, market research director, noted that uncertainty over U.S. import tariffs could weaken vehicle output and scrap volumes, posing downside risks. Margery Ryan, advocacy and market development manager, added that increased defence spending may drive additional PGM demand given their vital role in military and aerospace technologies.

One Minute Mentor: Distortion of High-Speed Steels

High-speed steels show a typical distortion behavior depending on the heat treatment parameters. The figure shows the change in length of cylindrical bars (diameter = 20 mm, or 0.8 in.) and length = 140 mm, or5.5 in.), with rolling direction longitudinal to the sample) for various heat treatment conditions with austenitizing, salt bath quenching, and double tempering.

Quenching and tempering up to 500 °C (930 °F) results only in very small changes in length (either growth or shrinking). Higher tempering temperatures lead to a transformation of the retained austenite into martensite and a corresponding growth in length. For typical tempering temperature of 560 °C (1040 °F) changes in length of about 0.2% take place. Additional alloying with Co (5%) leads to slightly higher changes in length. The effect of an additional third tempering shifts the curve slightly to the left, whereas oil quenching leads to a slight reduction of the change in length.

Solar Manufacturing receives US patent for a control thermocouple for vacuum heat treating furnaces

Solar Manufacturing,Sellersville, PA, announced that it has received US Patent #11,815,403 for an innovative control thermocouple design for vacuum heat treating furnaces. This new thermocouple offers a significant advantage in controlling operating temperatures from ambient up to 1200°F (649°C), particularly in smaller diameter hot zones of 36 inches (91.44 cm) or less.

In conventional control thermocouple designs, the outer ceramic protection tube acts as a heat sink under these conditions. This thermal conduction, or heat loss, is compounded by the shorter length of the thermocouple assembly, causing it to operate at a lower temperature. As a result, the furnace’s heating elements increase power output to maintain the set-point temperature, leading to a hotter workload temperature than the furnace temperature. This issue is more pronounced at lower processing temperatures below 1200°F (649°C).

The newly patented thermocouple configuration addresses these undesirable thermal conduction losses. It has demonstrated improvements in temperature uniformity survey results. Meeting AMS 2750 standard temperature uniformity specifications requires control thermocouples to be properly located within the hot zone for accurate survey thermocouple measurements without correction factors.
