casting sample meaning in English
浇铸样
Examples
- The fabrication of casting sample of normal male canine prostatic duct and acinus system
犬正常前列腺导管系统铸型标本的制作 - The cracks extend along the matrix / strengthening - phases interfaces and form the cleavage steps and tear ridges . there appear some very small dimples on the fracture surfaces of the directionally solidified samples , which come from the nb - based solid solution particles in the big plates of the strengthening phases , but no dimples on the fracture surfaces of the as - cast sample . it can be concluded from above results that niobium - niobium silicide based in - situ composites ( rmics ) with a uniformly orientated microstructure can be produced by the ebfzm with high temperature gradient , and their mechanical properties can be increased
随着抽拉速率的提高和硅化铌强化相间距与尺度的减小，材料的室温拉伸强度和断裂韧性均有提高， _ b最高可达778 . 4mpa ， k _ ( ic )达到了46 . 3mpa ? m ~ ( 1 / 2 ) ；试样的拉伸断口基本表现为脆性解理断裂的花样，裂纹沿基体强化相界面绕过强化相进行扩展，在裂纹扩展方向存在解理台阶，并形成撕裂棱。
