ABSTRACT
Rolling is the most important through-processing technology of metallic materials. The roll is an important part of the equipment in the process of rolling mill. Different types of rolls are used in different rolling processes. GB/T1503-1991 specifies one of the characteristics of rolls,......
The full penetration diamond core method is a viable and cost-effective process for accurately assessing the compressive strength of concrete, minimizing the risk of obtaining false or misleading test results. This method provides a reliable measure of the concretes strength, since it wets the e......

Method for Determining Intergranular Corrosion of Aluminum Alloys
Intergranular corrosion (IGC) is a type of corrosion that primarily occurs along grain boundaries in aluminum alloys. This type of corrosion occurs when certain alloying elements as well as nonmetallic inclusions are exposed to a......
GB/T 11351-89 Castings Weight Tolerances
GB/T 11351-89 specifies the weight tolerances to be used in weight inspection of the castings. Standard test pieces are provided for the determination of casting weight for comparison. This standard applies to all kinds of castings whose surface area is gr......
Steel has been used in many industrial fields in recent years, including automobile manufacturing, construction, and shipbuilding. According to the characteristics and application requirements of the industry, the alloy element content in the steel must be strictly limited, so as to ensure the qua......
