microstructure evolution of 42crmo4 during hot

  • microstructure evolution of 42crmo4 during hot

  • Generally speaking, the duration of the "exhalation" of the microstructure evolution of 42crmo4 during hot is longer than that of the "inhalation" of the microstructure evolution of 42crmo4 during hot every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the microstructure evolution of 42crmo4 during hot location, open area of the microstructure evolution of 42crmo4 during hot, atmospheric pressure, filling degree of microstructure evolution of 42crmo4 during hot, etc. When the microstructure evolution of 42crmo4 during hot is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.
