Reduces the upper shelf energy
Increasing the ductility transition temperature
Decreases brittleness
Decreases hardness
B. Increasing the ductility transition temperature
Are good conductor of heat & electricity
Act as electron donors with metals & as electron acceptor with non-metals
Are not necessarily solids at room temperature
Are compounds that exhibit both metallic & non-metallic properties to some extent and are exemplified by elements like germanium, silicon & boron

Hot worked materials are subjected to annealing to remove internal stresses
Annealing of steel hardens it slightly
Normalising of a material induces stresses
Tempering of a material improves ductility & toughness but reduces hardness & brittleness

More but less than the diameter of bolt
Its higher boiling point (290°C) increases its heat carrying capacity
Comparatively less weight of coolant is required
Smaller radiator can be used
