Due to multiple episodes of gold mineralization and multiple sources materials in ore-forming, there are heated debates on the era of the mine, and the main mineralization age of the Gupao gold deposit is focused on the Caledonian or Early Yanshanian.
The mineralization of it formed in several stages and its mineralizing materials originated from multiple sources [4, 5].

Therefore, the huge interest on the miniaturization of these materials can be easily understood.
We can classify bulk materials on the basis of these interactions and their influence on the materials behavior in response to magnetic fields at different temperatures (e.g. ferromagnetism, ferrimagnetism, etc.).
Indeed, bulk materials basically contain multiple magnetic domains due to their large size.

The temperature dependent mechanical and physical material properties for 316L stainless steel used in the analyses are detailed in [7].
The effect of phase transformation on residual stress and distortion was not considered important for the stainless steel material.
