Unformatted text preview: Hence coarse grain materials are preferred for applications at high temperatures. ♦ Creep can be operative at low temps if the material has relatively low melting points. Hence creep can occur in poymers at room temperature. ♦ Stainless steels and refractory metals are especially good for creep resistance. ♦ Factors that give materials good creep resistance: 1. high melting temperature 2. high elastic modulus 3. less grain boundaries...
