Development of NHT Alloys with Good Hot Cracking ...

2021-8-4  the casting of aluminum alloys.In most cases, the castings cannot be salvaged for further processing because of the hot cracking. Therefore, the control and eliminationof hot cracking are very important in casting alloy, process, and product designs. Hot cracking tendencies of aluminum alloys are significantly affected by alloy compositions.

Effect of hot isostatic pressing on cast A357 aluminium ...

The effect of Hot Isostatic Pressing (HIPping) treatments on porosity in the aluminium casting alloy A357 and stir-cast A357/15 vol % SiC particulate Metal Matrix Composite has been investigated. Densitometry and image analysis have been used to determine the apparent percentage porosity. Four HIPping temperature profiles have been investigated (103 MPa pressure) and mechanical testing has ...

Hot Forging forcebeyond

2 天前  Hot forging aids in making the metal easier to shape as well as less likely to fracture. Iron, along with its alloys, are almost always hot forged for two main reasons: #1) If work hardening progresses, hard materials (such as steel and iron) will become more difficult to work with, and #2) It is a more economical option to hot

CPP Films, Cast Polypropylene Films Manufacturer

Cast Polypropylene (CPP) films offer excellent heat seal strength, good thermal stability, good puncture resistance, good clarity and fair barrier properties. The film type also has good yield economics owing to its low density. Some of the typical application areas for the film includes hot filling and retort applications, high speed application on FFS machines and bakery products.

TearSim: A two-phase model addressing hot tearing ...

A two-phase mathematical model for the study of hot tearing formation is presented. The model accounts for the main phenomena associated with the formation of hot tears, i.e., the lack of feeding at the late stages of solidification and the localization of viscoplastic deformation. The model incorporates an advanced viscoplastic constitutive model for the coherent part of the mushy zone ...
