An Explanation of the Echo-to-Echo Measurement Technique Introduction: The ultrasonic echo-to-echo technique utilizes gates set around two consecutive backwall echoes and measures the difference between them. This difference negates the coating thickness and returns just the part thickness. The echo... Read More

Metallographic Sample Preparation Process Metallographic sample preparation usually includes sampling, inlaying, grinding, polishing, etching and other work processes, which require certain technical skills to support in order to produce qualified metallographic samples that meet microscopic ...

Metal Fatigue Failure and Characteristics Fatigue failure refers to the phenomenon that metal materials fail due to cumulative damage after a certain number of cycles under the action of variable loads. Fatigue failure has a certain degree of contingency and randomness, and the probability of ... Read More

What Are the Characteristics of Austenitic Stainless Steel? It is an austenite phase at room temperature. The Cr content is greater than 13% to increase the electrode potential of iron, thereby improving the corrosion resistance of the material. The Ni content is also high. On the one hand, it can ...

Cleavage Fracture of Metal Materials The fracture form of metal materials separated along a specific crystal plane under the action of tensile stress is called cleavage fracture. The plane where this fracture occurs is called the cleavage plane. Cleavage fracture is a brittle fracture. Cleavage ... Read More

Hardness Testing Method of Strip Steel Strip Steel Introduction: Strip steel is a narrow and long steel plate produced to meet the needs of different industrial sectors. Its width is generally within 300mm, but with the development of the economy, the width is no longer limited. Strip steel is ... Read More
