1·The low modulus of elasticity, higher tensile strength, good plasticity and toughness are the most important premise for surgical implants and orthopedic devices.

鉴于低模量、中高强度和良好塑性、韧性是医用合金作为外科植入物和矫形器械使用的重要先决条件。

2·The strength of the alloy foils with coarse grain microstructure was low, but the plasticity and elastic modulus were greatly improved.

粗晶组织阶段，强度很低，但塑性和弹性模量有较大程度提高。
