A Method for Determination of Constant and Varying Friction Factors During Ring Compression Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Available mathematical analyses have been applied to develop a reliable method for treating experimental results from ring compression tests with and without bulge formation to obtain quantitative ...
The Influence of the Interface Condition on the Plastic Deformation Zone and the Resultant Product Integrity in Extrusion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of the tooling-workpiece interface condition on the metal flow in extrusions is shown to be of critical importance in the achievement of sound product. For 2:1 reduction ratio ...
A Load Calibration Technique for Use on Large Industrial Presses and Small Testing Machines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A load calibration technique based on the plastic deformation of a ring specimen is described. The method is applicable to any size press at loads up to full capacity. The method consists ...
Plastic Deformation of Copper and Steel in Hot Extrusion Through Conical Dies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method of observing flow lines during metal forming was applied to the conical die extrusions of oxygen-free high-conductivity copper at 800 deg F and of SAE 1018 steel at 1800 deg F, ...
