Inconel 718 is a nickel-based superalloy of high interest in high temperature applications such as turbine *** be used in such applications,heat treatments are commonly applied to dissolute Laves phase and to achieve𝛾γ′***,conventional heat treatment methods for wrought Inconel 718 may not be suitable for Inconel 718 fabricated by laser directed energy deposition(LDED)due to its unique microstructure formed during the rapid solidification *** has been a lack of investigation in heat treatments for Inconel 718 fabricated by this process,specifically around the impact of aging parameters on this *** this study,the effects of aging parameters were studied by performing seven different heat treatments,including solutionising and aging *** results indicate that for LDED Inconel 718,a high temperature solution treatment of 1100℃for 1 h followed by single aging at 650℃for 20 h achieved a tensile strength and elongation of 1247 MPa and 23%,***,results indicated that even with a shorter aging time of 10 h,γ′phase was found to be of comparable size to the standard double aged treatment.

襄阳市急性冠脉综合征患者出院后服药情况和相关因素分析

目的观察和分析襄阳市急性冠脉综合征患者服药情况和相关因素。方法收集我院已诊断急性心肌梗死或不稳定型心绞痛患者,使用标准的问卷来研究患者坚持服药以及未坚持服药的原因,采用logistic回归分析出院后6个月与12个月的服药情况。结果在出院的时候药物治疗比例很高(98%服用阿司匹林,85%服用β-受体拮抗剂,97.8%服用他汀类药物),但是在随后的随访中服药比例是减少的。只有72%的出院患者同时服用4种药物(阿司匹林,倍他乐克,血管紧张素转换酶抑制剂或血管紧张素受体拮抗剂和他汀类药物)。而在出院后1年服药比例减少至52.9%,使用logistic回归分析提示在出院以及随访中,医疗保险、血脂异常、高血压病和介入治疗为重要的服药的相关因素,而医生对很大比例的患者服药情况未予宣教,部分药物费用过高也是影响坚持联合用药的原因。结论襄樊市已诊断急性冠脉综合征患者出院1年时按规范服药率为52.9%,影响服药依从性的因素是是否患有并发症、宣传不到位和费用高。
