The invention discloses a heat treatment process for improving the strength of an additive manufacturing nickel-based alloy FGH4098, and belongs to the technical field of metal additive manufacturing and heat treatment. Comprising the following steps: forming an FGH4098 alloy blank by adopting a selective laser melting (LPBF) technology; performing high-vacuum packaging treatment on the cleaned sample to construct a clean independent microenvironment; and then direct aging heat treatment at the temperature of about 760 DEG C is carried out. According to the method, a traditional high-temperature solid solution step is abandoned, and a micron-sized fine grain structure and a high-density dislocation network which are unique to a printing state are completely reserved; meanwhile, oxygen erosion in the heat treatment process is effectively isolated through vacuum packaging, oxidative depletion of key strengthening elements (Al and Ti) is prevented, and it is ensured that phases are fully dispersed and separated out in the pure environment. According to the invention, the problems of grain coarsening and softening caused by high-temperature solid solution and easy oxidative deformation in conventional aging in the prior art are solved, the tensile strength, hardness and dimensional stability of the alloy are remarkably improved, and short-process precision manufacturing of high-performance components is realized.

In reactive polycarbonates, there is a problem of poor reactivity in the crosslinking reaction. Furthermore, existing reactive polycarbonates that require minor components such as polymerization initiators tend to be unsuitable for various applications and have poor versatility. The above problems are solved by the polycarbonate resin of the present invention, wherein the polycarbonate resin comprises: structural units (A) derived from monomers represented by the following general formula (1) and / or structural units (B) derived from monomers represented by the following general formula (2); and structural units (C) derived from monomers represented by the following general formula (3), wherein the total proportion of structural units (A) and (B) is 0.5 to 25 mol% relative to the total molar number of structural units (A) to (C) constituting the polycarbonate resin, and the proportion of structural unit (C) is 75 to 99.5 mol%. R in formulas (1) to (3) 11 ~R 38 As shown in this application specification.

The application belongs to the field of medicine crystallization, and discloses a new crystal form II of Morlidstat and a preparation method thereof. P The crystal form II of Morlidstat is a triclinic crystal, a with a cell parameter of: b = 6.0316 Å, c = 7.2911 Å, α = 16.1027 Å, β = 101.098°, gamma = 90.447°, = 104.418°. The preparation process of the crystal form II of Morlidstat is simple, stable and highly reproducible. The crystal form II of Morlidstat obtained by the process is stable in crystal form, color and morphology under the condition of 30±5°C and 40±5% RH for 30 days, and the crystal form stability is significantly improved compared with the original crystal form, so that the crystal form II of Morlidstat is suitable for the manufacture and long-term storage of drug preparations. Compared with the Morlidstat sodium salt in the prior art, the crystal form II of Morlidstat has moderate solubility, so that the abnormal bioavailability caused by excessively high solubility can be avoided.
