Metlab hardens and press-quenches leaf springs for 1932 Alfa Romeo

January 13, 2014
Source:

Metlab, Philadelphia, recently heat-treated custom fabricated leaf springs of an antique 1932 Alfa Romeo sports car. The springs were fabricated for a Pennsylvania based automobile restorer. The leaf springs, made from HR-5160 steel, were patterned after the original springs, which were too worn to be reused. The replacement springs were hardened and press quenched into the shape of the spring, using a pencil-drawn template made from the originals. Then they were tempered to a final hardness of HRC 28–32, duplicating the hardness as measured on the samples.

Another recent project included the case hardening of reground lifters from a 1962 Rolls-Royce Silver Cloud engine. The lifters, which exhibited about 0.010-in. wear, were reground to make them all uniform in size. However, the grinding removed the hardened case, hence the lifters had to be recarburized and rehardened. As-measured surface hardness was HRC 62.

In addition, Metlab is often called upon to nitride O.E.M. as well as reground camshafts, crankshafts, and other engine components to restore these parts to original factory specifications. Camshafts are typically manufactured from 4140 or 4340 pre-heat-treated steel. This steel has a hardness of HRC 28 – 32. Nitriding results in a surface hardness of HRC 60+ and a case depth of up to 0.020 in., providing significant wear protection for the cam lobes and gear teeth.

In addition to hardening and surface treatment services, Metlab offers cryogenic processing on automobile engine, transmission, and brake parts for improving their performance extending their useful life.

QuesTek’s Ferrium M54 Steel included in aerospace industry MMPDS Handbook

Source:

QuesTek Innovations LLC, Evanston, Ill., announces that its ultra high-strength, high-toughness Ferrium  M54 steel has been approved for inclusion in the aerospace industry's Metallic Materials Properties Development & Standardization (MMPDS) Handbook. QuesTek accelerated M54 steel from a clean sheet design to a precise chemical composition in less than one year, and produced the first 10-ton ingot the following year.

SAE International issued an Aerospace Material Specification (AMS 6516) two years later. With this MMPDS approval, M54 steel has reached full flight qualification from clean sheet design in less than six years.

This marks QuesTek's second fully qualified alloy, following the 2008 MMPDS approval of its ultra high strength, high toughness, corrosion resistant Ferrium  S53 alloy, which is being used without toxic cadmium plating in landing gear and other corrosion-sensitive applications.

Integrated Computational Materials Engineering methodology and its Materials by Design technology have enabled QuesTek to design and develop M54 steel to be a cost-effective, drop-in replacement for AerMet 100. The alloy design project was funded under two Small Business Innovation Research contracts sponsored by the U.S. Navy Naval Air Systems Command.

The MMPDS Handbook provides standardized design values for alloys in aerospace structures, and is accepted by the Federal Aviation Administration, the Department of Defense, and the National Aeronautics and Space Administration. The A- and B-Basis design minima for M54 steel will first be published in MMPDS-09, allowing engineers to design components of M54 steel for flight safety critical components such as landing gear and helicopter rotor shafts. M54 steel is also an upgrade from 4340 and Maraging steel grades, and is being used in demanding oil and gas and other industry applications.

Digital image correlation system optically detects strain

Source:

Instron, Norwood, Mass., announces digital image correlation (DIC) hardware and software designed to optically detect strain and displacement. The DIC system enables users to visualize these changes in real-time on a computer screen, so that they can be traced over the entire duration of the test.

Image and calibration data are supplied by an Instron Advanced Video Extensometer (AVE). The associated DIC-software provides visualization and also saves the data at an adjustable rate of up to 50 Hz in the form of individual images for subsequent analysis in post-processing mode. The software runs independently of other programs, and leverages the graphical layout and tabbed style of Instrons Bluehill materials testing software – making the user interface familiar and easy to use.

The DIC technology provides numerous benefits compared to traditional strain measurement, including, for example, the documentation of phenomena such as discontinuous strain, localized necking, and more. DIC enables the detection of strains and displacements in cases where conventional extensometers are impractical, and enables the visualization of the side profile of flat bending or compression specimens.

The system also reveals cracks that are not visible to the naked eye. Finally, the DIC technology helps with standard compliance, as it identifies local strain that falls outside the standard gauge length of conventional extensometers.

The DIC software comes with a large number of standard functions. These include the generation of surface maps containing information on local axial and transverse strains and displacements, shear strain, and maximum and minimum normal strain. Further standard features include saving of processing parameters, graphical processing and the capability of synchronization with Bluehill® test data such as load, crosshead position etc.
