specific Embodiment approach 1
[0015] Specific implementation mode one: as Figure 1~5 As shown, the steps of the method for testing the high-temperature performance of metal sheets in this embodiment are as follows:
[0016] Step 1. Make metal sheet samples: select a metal sheet with a length L of 150-300 mm and a width W of 35-45 mm, take the center line of the metal sheet in the width direction as the X-axis, and take the X-axis as a symmetry on both sides of the metal sheet An isosceles triangular plate or an isosceles trapezoidal plate is cut off on each axis, and the angle α between the side wall of the metal plate that coincides with the oblique side wall of the cut-off isosceles triangular plate and the side wall of the metal plate is 5 to 10 °, the angle β between the side wall on the metal plate that coincides with the inclined side wall of the cut-off isosceles trapezoidal plate and the side wall of the metal plate is 5 to 10°, so that the middle width of the metal plate is W 1 It is 0.6 to 0.8 ...
specific Embodiment approach 2
[0023] Specific implementation mode two: as Figure 1~3 As shown, in the first step of the present embodiment, the metal sheet sample is selected to have a length L of 200-280 mm and a width W of 40 mm. Metal sheet samples of corresponding length and width can be selected according to different types of material tensile testing machines. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0024] Specific implementation mode three: as figure 1 As shown, the included angle α in Step 1 of this embodiment is 6° to 9°. The size of the angle between the hypotenuse of the isosceles triangle and the long side of the metal sheet can be selected according to the length of the sheet metal sample. Others are the same as in the first embodiment.
