Abstract
The paucity of metal powder for PM products manufacturer prompted an alternative sourcing. Brass chipspowder sourced from artisan workshops was characterized for standard PM process; a particle length of 140micron was obtained the resultant brass sinter was investigated considering some selected physical and mechanical properties of the 1.44cm diameter sinter.At a press load value of 45, 50, 55, 60, 65, 70 and 75 KN, a compact pressure of 245, 280, 310, 340, 370, 395 and 424 MPa resulted respectively.Congruently, tensile strength of each of the seven samples investigated reflected the following sinter strengths: 349, 360, 381, 408, 423 and 445 MPa respectively. However, there was a relative fall in sinter height with respect to increasing compact pressure from 2.12, 2.07, 2.01, 1.97, 1.92, 1.88 to 1.85cm. The total keeping time and sintering temperature of 30 minutes and 800 degrees Celsius were uniformly applied.The least square method of linear regression was subsequently applied; an expression for compact pressure (P) and Tensile strength (T): P1.78T 364 was developed at a coefficient of association of 0.995.
