Austenitizing temperatures for water-hardening tool steels normally vary from 760 to 845 °C (1400 to 1550 °F), as indicated in Table 2. Higher temperatures are sometimes used for special purposes (Fig. 2). Hardenability increases as austenitizing temperature increases. The optimum time at austenitizing temperature is from 10 to 30 min. Preheating is unusual except for very large tools or those with intricate cross sections. It is particularly important to protect shallow-hardening steels against scaling and decarburization. Severe scaling can interfere with heat transfer during quenching and slow the required high rate of cooling. Decarburization will produce a soft surface on any tool steel, but in a deep-hardening steel it can be ground off until the underlying hard high-carbon area is reached. Grinding a shallow-hardening steel will frequently expose the soft core.

Researchers from Lawrence Livermore National Laboratory (LLNL), Calif., created a new model for crystal defects at realistic temperatures. As most materials, especially metals and ceramics, are crystals, their atoms are arranged in three-dimensional lattices that repeat the same exact pattern, over and over again. But there’s a well-known saying in materials science: “Crystals are like people. It is the defects that tend to make them interesting.”

To determine what Earth was like early in its lifetime, researchers turn to minerals called zircons, which are resilient against physical and chemical alteration over time and thus preserve a precise chemical record about the moments in which they were formed. Some of the oldest zircon crystals are 4.4 billion years old. Now, a new study at the California Institute of Technology (Caltech) examines these most ancient zircon grains and discovers evidence for two key findings.

Blacksmiths fire metals before hammering them, as heat always softens metal, making it more malleable and easier to reshape. Or does it? In a surprising new study, engineers from Northwestern University (Evanston, Ill.) discovered that, in extreme conditions, heat does not soften pure metals—it strengthens them.

Stainless steel is widely known for its corrosion resistance. But when it is exposed to environments containing chloride ions, such as seawater, the risk of corrosion increases. Manufacturers typically grind the surface to smooth it. However, this finishing process reduces corrosion resistance even further. Researchers at Tohoku University in Japan have recently shed light on why this occurs.
