Which of the following is not a characteristic of hot-pressed material? Correct Answer Ductile
Hot pressed material is very hard, wear resistant and practically free from residual porosity. In this process, the powder mixture, without the presence of lubricant, is introduced into graphite dies and pressing and sintering operations are carried on simultaneously; the pressure varying from 0.5-2 tsi and the temperature from about 1300-1550°C with direct resistance or induction heating.
