Shear stress effcts on plastic instability and strain localization of ductile metals under plane strain tension are discussed in this paper.

In this paper the effect of ultrasonic action on the mechanical behaviors of ductile metal materials is investigated by both experimental and theoretical approaches.

Thermal simulating the microstructure in weld heat affected zone of calcium microalloyed C-Mn steel and its effect on toughness;

Effect of EAF-VOD-VAR and VIM-VAR Metallurgical Process on Toughness of Ultra-high Strength Steel G50;

Effect of granular bainite in microstructure after welding on impact toughness for micro-calcium steel;

Melamine formaldehyde resin is a thermosetting polymer,spinnability and flexibility of fiber are poor.

The results of the experiments show that the grain size of the carbon strips reduces with the decreasing of the thickness;the general mechanical properties and formability of the carbon strips are preferable;the flexibility of 5.

Study on The Quantitative Relationship Between The Forms of Carbides and The Tenacity of Abrasion Resisting High Chromium Cast Irons;

Various performance test results showed that the product possessed good toughness and tenacity,excellent thermal stability during storing and good road performance at high-low temperatures.

The steel wire was broken heavily and the tenacity of steel wire was worse with the general drawing process when manufacturing steel wire of high quality,qualified products proportion is low.
