| Abstract | ||
| This paper presents the Taguchi approach for optimization of hardness for shape memory alloy (Cu-Al-Ni) . The influence of powder metallurgy parameters on hardness has been investigated. Taguchi technique and ANOVA were used for analysis. Nine experimental runs based on Taguchi’s L9 orthogonal array were performed (OA),for two parameters was study (Pressure and sintering temperature) for three different levels (300 ,500 and 700) MPa ,(700 ,800 and 900)oC respectively . Main effect, signal-to-noise (S/N) ratio was study, and analysis of variance (ANOVA) using to investigate the micro-hardness characteristics of the shape memory alloy .after application the result of study shown the height hardness at the level 2 of pressure and level 1 of temperature (A2B1) by taguchi technique at magnitude value 500MPa and 700 ºC. The best effective factor at ANOVA has pressure 36.39%. the interaction given the best pressure 500 MPa and Temperature 800 ºC. | ||
