Countermeasures to Prevent and Eliminate Grain Inheritance in Forging
The Prevention and Elimination of Grain Inheritance in Forging
Introduction
Grains inheritance has been found to be one of the major causes of defects in forged parts. It occurs during the deformation process of the work material when internal stress is introduced, leading to poor grain structur......
Forging technology: titanium alloy forging quenching, aging heat treatment
Abstract
Thestudy concentrates on the formation of titanium alloy forgings by press& forging, quenching and tempering, aging thermal treatment process. The purpose of this technology is to improve the structure and properties of titaniumalloy forgings, thereby improving the strength and toughness......
Effect of Austenite Dendrite on Shrinkage Porosity
Austenite Branch Crystals on Residual Stress
Crystal structures are the set of atoms that make up the bulk of a material. Austenite, for instance, is a crystal structure that is a type of iron-carbon alloy, with carbon interspersed between iron atoms in the crystal lattice. Austenite branch cryst......
Properties of carbides in white cast iron
The Properties of Carbon in White Cast Iron
White cast iron, also known as non-malleable cast iron, is a type of cast iron containing a high amount of carbon and nearly no alloying element. When white cast iron is cooled rapidly, the carbon forms into small particles within a matrix of iron and f......
The role of alloying elements in white cast iron
The Role of Alloy Elements in White Heart Malleable Cast Iron
Whiteheart malleable iron, also known as whiteheart malleable iron, is a kind of cast iron based on pearlitic matrix and rare ductile iron. It is characterized by high strength, low hardness, large elongation and plasticity and impact ......
Hot cracking of steel castings
The importance of control of thermal cracks of steel castings
Introduction
Thermal cracking occurs as a result of the uneven cooling of steel during the casting process. It is a common problem in the production of steel castings and requires special attention to its prevention. Properly controll......
Effect of High Temperature Heating Conditions on Depletion of Alloying Elements
The Effect of High Temperature Heating Condition on Depletion of Alloy Elements
As an important metal material, alloy has been widely used in many fields because it has the advantages of good comprehensive performance and strong stability. Among them, the metal element in the alloy plays an impor......
Basic structure characteristics of gray cast iron
Introduction
Gray cast iron is a kind of cast iron with the main constituent elements of iron, carbon and silicon. It is an alloy material that has been widely used in automobile, machinery, heat exchanger and other fields due to its good casting performance, low cost and good mechanical properti......
Matrix structure characteristics of gray cast iron
Gray Cast Iron Microstructure
Gray cast iron is an iron-carbon alloy mainly composed of iron, carbon and silicon. It has good castability, high strength, good machinability, excellent vibration damping and other advantages, so it is widely used in automobiles, machines, chemical processes and mar......
