奥氏体(英语:Austenite)或ɣ-Fe,是鋼鐵的一種顯微組織,通常是ɣ-Fe中固溶少量碳的無磁性固溶體[1]。奥氏体的晶体结构为面心立方,其溶碳能力较大,强度低,可塑性强,膨胀灵敏,无磁性,有一定韧性。沃斯田鐵的名稱是來自英國的冶金學家威廉·钱德勒·罗伯茨-奥斯汀[2]。
铁素体在912°C至1394°C時會相變成沃斯田鐵,由體心立方的結構變成面心立方。沃斯田鐵強度較低,但其溶碳能力较大(1146°C時可以溶進2.04%的碳)。[3]沃斯田鐵系列的不锈鋼常用於食品工業和外科手術器材。

This is an entry in the Fortnightly Topic Challenge #41: Short and Sweet. 1 letter only could be mean anything . With an additional letter in front , could be used as medicine component and something you definitely learn or at least heard once. Add another letter in front , you would possibly hear that many times . Add an additional letter in front , you would found an independent country . With an additional letter, in the end , you would found something related to apple . Add another letter in the end , you would found something bad . Hint: Each letter is unique .

I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers?
