This invention provides a TiC-based non-magnetic alloy, its preparation, and its application. The TiC-based non-magnetic alloy comprises, by weight percentage: Ni 25–40 wt%, Cr 5.5–8.6 wt%, Mo 2.5–4.0 wt%, C 0.8–1.3%, TiC 46–66 wt%, and other unavoidable trace impurities. The TiC-based non-magnetic alloy comprises TiC, Ni, Cr, Mo, and C, with appropriate proportions of each component, resulting in low magnetic properties, high hardness, high wear resistance, high-temperature performance, oxidation resistance, and corrosion resistance. Furthermore, the hard phase uses TiC, which has a low self-lubricating coefficient, and excludes WC. Therefore, the TiC-based non-magnetic alloy has a uniform grain size distribution, good internal stress consistency, and is less prone to cracking and deformation, extending its service life and demonstrating good product stability.

This utility model relates to the field of high-gloss wall panel technology, specifically a crack-resistant high-gloss wall panel, comprising a first substrate board, a second substrate board disposed on one side of the first substrate board, a quick-assembly mechanism disposed on the surfaces of the first and second substrate boards, a crack-resistant mechanism disposed inside the first substrate board, and a sound-dampening mechanism disposed inside the first substrate board. This utility model not only significantly improves the assembly efficiency between the first and second substrate boards during use, making the high-gloss wall panel more convenient for users to operate, but also increases the overall strength of the high-gloss wall panel, making it less prone to cracking and more durable. Furthermore, it reduces noise interference, improving users' sleep quality and quality of life, reducing the impact of noise on the wall structure, and extending the building's lifespan.
