gray cast iron

Figures (a) ~ (d) are metallographic photos of vanadium titanium gray cast iron with different components. It can be seen

1. Composition design In order to understand the influence of vanadium, titanium, carbon and silicon content on the microstructure and

The thermal fatigue resistance of gray cast iron can be characterized by its tensile strength at corresponding temperature, which has

1. Tensile strength test The experimental results of tensile strength of samples after different high temperature oxidation cycles are shown

1. High temperature oxidation cycle test The size shall be 30 mm in a muffle furnace × 30 mm ×

Gray cast iron is a common material for the production of ingot mold, chassis, sintering grate and industrial valves. Its

The samples of gray cast iron were treated by isothermal quenching and boronizing. The isothermal quenching process of gray cast

General materials contain some alloy compound phases. The existence of alloy compound phases enhances the matrix strength, hinders the crack

For cast iron, there will always be some unavoidable casting defects, such as shrinkage cavity and porosity. Casting defects have

The table shows the effects of the same alloying and different inoculants on the mechanical properties of gray cast iron.

The deformation of any material under external load will be affected by its own microstructure and properties and external environmental

For gray cast iron, its mechanical properties mainly depend on the matrix structure and flake graphite in it. The shape

The instantaneous fracture zone of fatigue crack is the area where the material is unstable and suddenly fractured. Due to

The fatigue crack growth region is the region of stable development after fatigue crack nucleation and initiation. Fatigue bands generally

The fatigue crack origin region is the region where the fatigue crack nucleates and initiates. The fatigue crack first nucleates
