Fatigue Fracture Analysis of an Mn-Ni-Co Alloy Sample
Abstract
Fatigue fracture analysis of an Mn-Ni-Co alloy sample was conducted to assess its fatigue properties. The sample was put under cyclic tensile load and tested at various constant amplitudes up to the fatigue limit. The f......
Metallographic diagram of W6Mo5Cr4V2 (heating, quenching and oil cooling at 1220°C)
At a magnification of 500X, the microstructure of CrW6Mo5V2 steel heated to 1220℃ followed by oil quenching can be observed through a Scanning Electron Microscope (SEM). The polished cross sections were used to view the microstructure by SEM. Dislocations, grain boundaries, and pro-eutectoid ferr......
3Cr13 (annealed) metallographic diagram
Introduction
The AISI 420/3Cr13 is a martensitic stainless steel containing 13% chromium. The alloy is heat treated to reduce hardness to the desired level. Heat treatment softens the material, improving its formability and machinability and increasing corrosion resistance. As an alloy, 3Cr13 is ......
Ferrite needle intergranular fracture
Abstract
This paper is a study of the application of iron-base needles on brittle fracture cracks. Brittle fracture is a major challenge that needs to be solved in order to ensure the performance and life of engineering materials. Iron-base needle technology is one of the potential methods for br......
Quantitative Metallographic Techniques
Quantitative Metallography
Quantitative metallography is the application of metallography to accurately quantify the microstructures of materials. This type of metallography is used to find the properties of a material through analyzing its microstructure and chemical composition. The use of quan......
Analysis of Longitudinal Crack of 195 Connecting Rod Along Parting Surface
Fatigue Analysis of Longitudinal Crack on the Split Module of a Crank Shaft of A 155/195 Models
Abstract
The 155/195 models of a crank shaft used an 169 split module to create an open-ended mating surface between two connecting arms. This split module was used to reduce overall manufacturing tim......
Metallographic diagram of 20Cr and Q235 (20Cr steel friction welding after carburizing and quenching)
The microstructure and properties of Q235 and 20Cr steels
The strength and other properties of many materials are determined by their microstructure. In this study, the microstructure and properties of Q235 and 20Cr steels are compared. 20Cr steel is an improved version of Q235, which is a low-al......
