Effect of Compaction Pressure and Sintering Temperature on Shape Effect and Compression strength of Cu-Al-Ni Shape Memory Alloy
Shape Memory Alloys (SMAs) are types of smart materials (SMs) which are used in many industries nowadays. The samples manufacturing smart alloy composed of copper alloy ,aluminum and nickel .The mixing materials weight percentage are 83% wt Cu - 13% wt Al-4% wt Ni .Has been followed by the compacting process .The powder compacted with three different value of the pressure (300,500,700) MPa. The sintering process has been in tube and vacuum furnace sintering environment at three different values of sintering temperature values (700,800,900)oC conducted the necessary tests, a screening of resilience and examination of compression for all samples. The experimental test for the samples showed that the highest value for the resilient be at a pressure of 700MPa and at a sintering temperature of 900oC either check compression straight was the highest value at a pressure of 300 MPa and temperature sintering 900oC.
