Modeling and optimization of precipitation hardening heat treatment factors of Al2024 alloy using a two-level full factorial design
In the current study, the sources of variation in the mean hardness value of heat treated aluminum 2024 samples were identified by using metallurgical study and design of experiment methodology (full factorial method). Hardness measurements and microstructural investigations of the samples were carried out using Brinell hardness test and optical microscopy, respectively. The effects of several ...
متن کاملIdentification of dispersion effects in replicated two-level fractional factorial experiments
Tests for dispersion effects in replicated two-level factorial experiments assuming a location-dispersion model are presented. The tests use individual measures of dispersion which remove the location effects and also provide an estimate of pure error. Empirical critical values for two such tests are given for two-level full or regular fractional factorial designs with 8, 16, 32 and 64 runs. Th...
متن کاملJoining of Cold-Reduced Carbon Steel Sheet and Aluminum Sheet by Impulsive Riveting Method and Punch Riveting Method
The impulsive riveting method is described as the punching and joining of sheet metal carried out using the impulsive energy of a weight accelerated by an air compressor. Parts are held together between the rivet and rivet-holder. A hole is made in the sheets by the high speed collision of rivet and a weight (approximately 100 m/s or more). Another method, punch riveting, joins the sheets by pr...
