大尺寸γ'
1.
The results indicate that there is a strong relation between the characteristics of previous particle boundary and oxygen content,when the oxygen contentis below 40 ppm,previous particle boundary is constitutded of big size γ′ mostly,when the oxygen is beyond 70 ppm,previous particle boundary is constituted of MC carbide mostly.
当氧的含量低于40×10-6时,原始颗粒边界主要由大尺寸γ′组成,这种原始颗粒边界不会对合金的力学性能产生影响;当氧的含量大于70×10-6时,原始颗粒边界主要由MC型碳化物组成,这种原始颗粒边界将对合金的力学性能产生不利影响。
补充资料:工程图标准尺寸及坐标尺寸
标准标注类型,是我们常用的标注类型。而坐标标注是便于数控加工采用的另一中标注形式。PRO/E可以将两种标注方式进行转换。
· 3.2 标准标注到坐标标注的转换
注意: 转化为坐标标注的尺寸必须是线性标注的,下列尺寸不能转化为坐标标注:
- 被显示成线性尺寸的直径
- 中心线尺寸
- 选择MODIFY DRAW > Dim Params > Dim Type > Ordinate Dim > Create Base.
- 选择作为参考基准线的尺寸
- 选择基准的引出线,该点为0点
- 选择 MOD DIM TYPE > Lin to Ord .
- 选择线性尺寸:注意:必须选择具有相同基准的尺寸
========>>>>
1. 选择 DIM PARAMS > Diam Dim Type .
2.点击Ord to Lin
3.选择尺寸即可
