Explore how temperature changes affect the stiffness of metals and alloys used in elastic components.
This study measures how the modulus of rigidity and Young’s modulus vary from —50° to +50° C across 31 metals and alloys, with results shown for each material in its practical heat-treated or cold-worked forms.
This edition presents the experimental approach, data reductions, and interpretation, focusing on how heat treatment and processing influence temperature coefficients. It highlights how these coefficients evolve with temperature and discusses implications for aircraft instruments and precision springs.
- Temperature coefficients for the modulus of rigidity and Young’s modulus across a wide material set.
- The effect of annealing, cold working, or tempering on temperature behavior.
- Comparisons of coefficient ratios at different temperatures to gauge variation.
- Discussion of Poisson’s ratio temperature behavior and related elastic properties.
Ideal for readers of engineering materials and instrument design, especially those evaluating performance across temperature ranges.
