Guinier-Preston zone strengthening. Precipitation hardening in the age-hardening stage of the heat-treatment process starts with the formation of Guinier-Preston (GP) zones. The formation of GP zones which occurs firstly by GP1 zones and then GP2 zones is illustrated in Fig. 4.23. Abstract In order to examine the scattering of conduction electrons from Guinier-Preston (GP) zones, the electrical resistivity (ρ) and the Hall coefficient have been measured.

Om wraak te nemen voor de manier waarop zij door hun voormalig werkgever op straat zijn gezet, stelen zij de gegevens en gaan zij nog eenmaal samen het avontuur aan.

A compressive stress applied during an early stage of ageing promotes formation of the platelet precipitates on the cube planes subjected to the largest normal stress.Discovery of Guinier-Preston zone hardening in refractory nitride ceramics.
