Figure 18.8 Variation of fracture toughness with yield stress
example, styrene-acrylonitrile (SAN) is brittle and far from tough. It can
however be toughened with the rubber polybutadiene to give the tougher
acrylonitrile-butadiene-styrene (ABS) (see section 15.1 and Figure 15.2).
18.6 Selection for creep and temperature resistance
The creep resistance of a metal can be improved by incorporating a fine
dispersion of particles to impede the movement of dislocations (see section
8.2). The Nimonic series of
alloys,
based on an 80/20 nickel-chromium alloy
