“…where C(θ) is elastic modulus tensor (unlike [28] dependent on the actual temperature of the rotor nodes θ at the time step considered [29]), β the thermal expansion tensor, in this particular case both reduced to scalars and θ0 the reference temperature. The linear strain is obtained simply as:…”

“…The Mg 2 Si compound provides strength and hardening in the form of a fine dispersion of particles in the alloy. 49 According to Qin et al, 50 an intermetallic compound of Mg 2 Si contributes good mechanical properties to alloy by providing high hardness, reasonably high elastic modulus and low thermal expansion. The size of Mg 2 Si is detected fine in this work as contribution of CS plate mechanism and it was supported by Qin et al 50 The flow of the melt on the CS plate is one of the factors that influences the fineness of the compound.…”

This article examines the evolution of the microstructure of A319 aluminium alloy as it flows along a cooling slope plate and discusses the type and influence of the intermetallic compounds thus formed. Numerous past research studies have analysed the microstructural transformation of alloys in a mould, but few researchers have investigated this phenomenon on the cooling slope plate. A change in the microstructure of the alloy from dendritic to non-dendritic is clearly obtained as the alloy moves from the impact zone to bottom zone on the cooling slope plate. It is important to clarify the mechanism of microstructural evolution through nucleation and fragmentation of the primary phase arm for fundamental understanding of research. Analysis by optical microscope and scanning electron microscope reveals the evolution of the microstructure and intermetallic compounds of A319 as it progresses along the cooling slope plate. The Vickers test was used to determine the hardness of the alloy thus produced. The results show the influence of the mould in obtaining a spheroidal microstructure; the microstructure in the bottom zone of the cooling slope plate is nearly spheroidal rather than fully spheroidal. The hardness of the alloy is enhanced when the microstructure is spheroidal and when the Mg 2 Si compound is present in the alloy.

“…The research methods of thermal fatigue properties are as follows [4]: strain range-thermal fatigue life, strain range partitioning method, equivalent temperature method, temperature amplitude-the number of thermal cycle method and average/maximum temperature-thermal cycles law. because of the complexity of thermal fatigue test, people try to use the high temperature mechanical fatigue test to replace thermal fatigue one [5][6][7]. while the constant high temperature mechanical fatigue does not reflect the range of temperature and strain, it is not reasonable enough to use.…”

Thermal fatigue tests are carried out to the notch specimens made of particle-reinforced composites entitled SiCp/A356 between 20°C and 300°C. The thermal elastic-plastic finite element method is used to simulate the stress and strain response at the notch root of the thermal fatigue test specimen, and thus the formation mechanism of residual stress is revealed. Then according to the finite element simulation of the stress-strain, the thermal fatigue strain life curves of SiCp/A356 material are given considering the residual stress. This can give the basis for the thermal fatigue properties study of the particle reinforced composite SiCp/A356 used in high-speed train brake disc.
