精美，又欣赏到leomet老师的精彩作品了

Good for you !.............

Hello, Mr. Wu, matrix which is close to twin boundary is always short of carbide particles, can i say that it was twin boundary carbide the cause the shortage of carbide particles?

Yes, you are right. Carbon atoms gather at twin boundary to form carbide, so there is always a carbide-free zone/band (PFZ) beside twin carbide, and boundary carbide as well.

該試樣繼續浸蝕下去, 基地腐蝕更深, 碳化物突出更高, 對焦效果就不好了.

Note that the twin carbide plates sticking out of the matrix more.

They act as blade and cut open the matrix of the steel.

今天又照了些彩蝕的........................

What the wonderful photomicrograph!
It's the first time for me to view the twin carbide.
Thanks, Mr. Wu

Thanks, M ...

It took me 30+ years to see this for the 2nd time.

老師好，

你的資料是真實的么？

你是台灣大學畢業的？在哪裡任職？

大師級人物，可否認識一下？

Maybe the server is not located in China Mainland.

As you know nearly all the overseas server ,such as Hongkong，Macau，Taiwan area，or some other foreign countries， is forbidden here.

X46Cr13 fatigue fracture surface....................

Tooling failed in a few weeks. So, customer sent it back for complaint.

Microstructure of this tooling.

Lots and lots of twin and grain boundary carbides which are
very detrimental to the toughness of any tool steel. These carbides appeared
after billet forging. But the problem originated from a poor diffusion annealing, or, soaking
of the ingot.
