Abstract:

The present study aims at investigating the effects of microstructure on fracture toughness of two A356 Al alloys. These A356 alloys were fabricated by casting processes such as rheo-casting and casting-forging, and their mechanical properties and fracture toughness were analyzed in relation with microfracture mechanisms. All the cast A356 alloys contained eutectic Si particles mainly segregated along solidification cells, and the distribution of Si particles was modified by the casting-forging process. Microfracture observation results revealed that eutectic Si particles segregated along cell

The metallurgy of cast aluminum alloys has always been considered to be different from that of wrought alloys.

Rupture occurred in the primary creep regime, with the eutectic alloy having the longest times to failure. Primary creep was modeled by Jt=A+Btn with A, B, and n dependent on stress. Poor creep performance is linked to the brittle fracture of the primary silicon phase as well as other casting defects.

Abstract:

The economic feasibility of using aluminum as a conductive material is explained by the favorable ratio of its cost to the cost of copper. It is also important that the cost of aluminum for many years remains virtually unchanged.When using conductive aluminum alloys for the manufacture of thin wire, winding wire, etc. Certain difficulties may arise in connection with their insufficient strength and a small number of kinks before fracture. In recent years, aluminum alloys have been developed, which even in a soft state have strength characteristics that allow them to be used as a conductive mat

Abstract:

211Z is a new type of high strength and toughness Al-Cu-Mn casting aluminum alloy. With the aid of GPS-100 high-cycle fatigue testing machine and DDL100 multifunction tensile testing machine, conventional mechanics performance tests and high-cycle fatigue tests were carried out in this paper. The conventional mechanical property results show that the tensile strength is 477.5 MPa, the theory yield strength is 397.5 MPa and the elongation is 6.625%. Fatigue experiments were performed with load control at room temperature and R =-1 in ambient air. The tensile and compression fatigue strength is

Abstract:

Two kinds of aluminum alloy, 1561 and 1565 alloys, were tested in parallel within impact velocity range of 250–750 m/s in two schemes of shock loading: (i) under uniaxial strain conditions and (ii) in high velocity penetration. Combination of load regimes allows a formation of multiscale structure to be retraced. In both schemes of dynamic loading, the transition into structure-unstable state and change of scale level of dynamic deformation was found to occur under identical impact velocities. Formation of mesoscale-1 (1–10 µm) for both alloys is found to be identical – the mesoscale-1 structu

In this paper, the microstructure analysis and performance research of dual laser beam welded 2060-T8/2099-T83 aluminum–lithium alloys were carried out. First, the macroscopic morphology and microstructure characteristics of T-joint aluminum–lithium alloys under different welding conditions were observed. Then the effect of welding parameters and pore defects on tensile and fatigue properties of the weld were carried out and the experimental results were analyzed. It was found that the weld heat input has a significant influence on the penetration of the welded aluminum–lithium alloys joint. W

Abstract:

The utilization of cast aluminum alloys in automotive industry continues to rise because of consumer demand for a future generation of vehicles that will offer excellent fuel efficiency and emissions reduction, without compromising safety, performance, or comfort. Unlike wrought aluminum alloys, the cutting speed for cast aluminum alloys is considerably restricted due to the detrimental effect of the alloy’s silicon constituencies on tool life. In the present study, a new wear model is developed for tool-life management and enhancement, in a high-speed machining environment. The fracture-mecha

Abstract:

We have developed a new testing device which is capable of detecting hydrogen gas release during slow strain rate tensile testing (SSRT) under ordinary pressure. The device is composed of an SSRT machine equipped with a closed chamber with an inspection window that is connected to gas chromatography with a semiconductor hydrogen sensor. Local strain distribution in the specimen during the SSRT is monitored dynamically with a digital image correlation (DIC) method. Hydrogen was pre-charged to aluminum alloys by means of friction in water process. Using the device, it was shown that hydrogen was
