Curtin University PRRE1003 Resources, Processes & Materials Engineering Workshop P5: Non-Metals and Manufacturing. Questions & Answers

Document Content and Description Below

LEARNING OUTCOMES • Understand and iden+fy the structures and behaviours of various non-metals • Understand the ini+al concepts of materials manufacturing Ac0vity 1: Ceramics and Glasses (40 mi... nutes) a) On the sketch below of specific volume vs temperature, the cooling paths of a crystalline solid and an amorphous solid have been drawn. Use your mouse to move the list of labels to the correct posi+ons and fill in the Table below. Amorphous solid Crystalline solid Structure upon cooling It does not crystallise due to the different volume sizes of the atoms will not reach the form of a solid. Amorphous reaches a certain temperature where it acts like a solid; allowing it to bear a load. Crystalline liquid starts to contract when cooling. When the liquid reaches a certain temperature point it crystallises coming s solid. Reducing the volume, shown with the rapid decrease of line 1 Change in specific volume Volume gradually decreases due to lowing of temperature, but will not reach a solid form. The structure remains disordered due to the different par+cles in an amorphous solid, and will not be able to reargue themselves to form a solid, because of this the volume is larger than a crystallised solid Reducing the volume, shown with the rapid decrease of line 1. This reduce in volume is due to crystalline solid’s par+cles able to arrange themselves in an order. This results in a solid formed. [Show More]
