#TZM When making TZM head, the additional carbon content is mainly based on the following considerations: First, improve material performance Enhance high temperature strength and creep resistance: Carbon as a gap element, in TZM alloy and molybdenum matrix replacement elements (such as titanium, zirconium) react with each other to form a spherical compound carbide particles precipitation. This dispersion strengthening mechanism can significantly improve the high temperature strength and creep resistance of molybdenum, and make TZM head work better in high temperature and harsh environment. Increase the recrystallization temperature: The addition of carbon helps to increase the structural stability of TZM alloy and increase the recrystallization temperature, thus extending the service life of the material. Secend. Meet the requirements of specific application scenarios TZM head is mainly used for perforating seamless steel pipes, such as stainless steel, brazed steel, high temperature alloy steel, molybdenum and other special parts. These materials need to withstand extreme conditions such as high temperature and high pressure during processing, so the material properties of the head have extremely high requirements. By increasing the carbon content, the high temperature resistance and creep resistance of the TZM head can be further improved to better meet the needs of these special application scenarios. Third. Process control Although increasing the carbon content can improve the performance of the TZM head, it also requires strict control of the production process. In the preparation process, it is necessary to ensure that the density and crystal structure meet the requirements to ensure the overall quality of the TZM head. Summary In summary, the additional carbon content when making TZM head is to improve the high temperature strength, creep resistance and recrystallization temperature of the material, so as to meet the needs of specific application scenarios. At the same time, this also requires strict control of the production process to ensure the overall quality of the TZM head.

Beryllium is a light and rare metal with a small atomic number and low density (only 1.847g/cm³), about 2/3 of aluminum and 1/2 of titanium. High melting b point (1283℃). Beryllium is α-Be at room temperature and has a dense hexagonal structure. The phase transition occurs at 1254 ° C and the structure is β-Be. Beryllium has the greatest heat capacity of all metals. With a specific heat capacity of 1.8828 J/gK at room temperature, beryllium absorbs more heat than other metals, and this property is maintained until the melting point. The thermal conductivity of beryllium at room temperature is 0.15kW/(m.K). The thermal expansion coefficient of beryllium is comparable to that of stainless steel and Ni-Co alloy. The thermal diffusion performance is also very good. Beryllium has a reflectance of 50% to visible light, 55% to ultraviolet light, and 98% to infrared (10.6m). It has a high penetration rate (almost transparent) to X-rays, about 17 times that of aluminum, and is an indispensable material for X-ray Windows. The elastic modulus of beryllium is very high (309,000 MPa), about 4 times that of aluminum, 2.5 times that of titanium, and 1.5 times that of steel. Especially in the temperature range from room temperature to 615 ° C, the specific stiffness is about 6 times that of steel, aluminum, and titanium. In addition, the thermal neutron absorption rate of beryllium is the smallest among all metals, while the scattering cross section is large. In addition, beryllium is a steel grey metal light metal. Beryllium is harder than its peers, unlike calcium, strontium, and barium, which can be cut with a knife.

📰 Surface Roughness Studies on F357 Aluminum Alloy Fabricated Using Laser Powder Bed Fusion Process ✍ Jaskaranpal Singh Dhillon, Su Su, Oscar Sanchez Mata, Tejas Ramakrishnan and Mathieu Brochu #Aluminum #alloys processed using laser powder bed #fusion are attracting industrial and research efforts striving to achieve the lightweighting potential and combination of good mechanical and corrosion properties. In this study, border parameter optimization for #F357 (AlSi7Mg) alloy processed using LPBF was performed with the aim of reducing the as-fabricated surface roughness. The #optimization revealed that laser power and scanning speed can significantly influence the surface roughness of cube vertical surfaces. Measured areal average surface roughness (Sa) for cube samples varied from 15 to 24 µm. The cube-based optimized parameters were used to fabricate angled wall samples with angles ranging from 45° to 90°. The surface roughness reduced when the built angle increased from 45° to 75°, while for 75–90°, the surface #roughness values remained constant.
