由于塑性区的影响,挤压纯镁的断裂韧性随着晶粒细化而增加,这是与屈服强度、断裂伸长率和应变硬化指数等力学性能相关的敏感因素。
The fracture toughness of extruded pure magnesium increased with grain refinement due to the effect of the plastic zone, which is a sensitive factor related to the mechanical properties of yield strength, elongation-to-failure and strain hardening exponent.
