Atlas of Stress-strain Curves


Book Description

Contains more than 1400 curves, almost three times as many as in the 1987 edition. The curves are normalized in appearance to aid making comparisons among materials. All diagrams include metric units, and many also include U.S. customary units




Thermomechanical Processing of Molybdenum-hafnium-carbon Alloys


Book Description

A study was made of the thermochemical processing of a series of Mo-Hf-C alloys. The processes either produced an overaged carbide precipitate within a strain hardened matrix or allowed the formation of a finer precipitate during fabrication by a dynamic strain aging reaction. The short time tensile properties of the strain aged alloys were superior to those of any other molybdenum alloy studied to date.
