Conclusion: Ni-Ti shape memory alloy stent is convenient and feasible in treating postoperative urethral stricture of hypospadia, and it has higher safety, small wound and definite curative effect.
It was reported that the detwinning stress in martensite of Ti-Ni alloys increases with increasing annealing temperature, but the reason for such a strange behavior has remained unclear.
The star cracks in macrostructure appear in some hypo-peritectic continuous cast alloy blooms and these cracks cannot be stuck completely by hot rolling reduction ratio,macroetching testing and SEM.
The alloy layer of tinplate is an intermetallic compound formed between base plate and tin coating through thermodiffusion during the treatment of heating and fusing after electrotinning.
The metabolism of hydrogen which involved hydrogenase was the main reason for the MIC of AZ91 alloy.The SRB accelerated the cathodic reaction through the cathodic depolarization.
Based on the principle of thermodynamics, the authors have made much calculation of the thermal effect caused from oxidation and generation of monodrome alloys and slag.
In this paper,the mechanism of workpiece burn during grinding of casehardened steel and titanium alloys was studied by the use of SEM,EPMA,XPS and the metallograph analysis.
