Testing and calculating method
of stress and deformation:
The workpiece is prepared at
*0×**0mm, with 5 full waves included and cut at wave
crests.
1． σ1=P/S,
where P is the pressure (N) to press the workpiece wave crest to
the *0% of its initial height between two plates, while S is the
respective projective area (mm2) of the workpiece.
2． K1=(a-a1)/a, where a is
the initial wave height, while a1 is the wave height after thermal
press treatment（Press the workpiece to plan, and keep it for *4
hours at **0±2oC, then cool it down to room
temperature）。
3． K2=(σ*-σ2)/σ2, where σ2 is
the *0% deformation stress after thermal press treatment, which is
tested in the same way asσ1.
4． K3 and K4
are corresponding to K1 and K2 respectively after aging ( Press the
workpiece to plan, and keep **8 hours at **0±2oC, then cool down to
room temperature and take out).
