The lifetime of power plants materials is determined by the creep and the steam oxidation resistances of the materials working at these conditions.
Ferritic steels are usually applied as structural materials in electrical power generation At 650ºC in steam environments, the oxides formed on ferritic steels are less protective than that formed at lower temperatures.
Target material.

X90, X100 pipe) is used to lay long-distance transmission gas pipelines due to the increasing demand for natural gas of our country, which could not only increase transmission pressure but also lower the cost of raw materials by reducing wall thickness of pipes and cutting down weld consumables.
So solving the problems such as welding properties, matched welding material and weld processes is good for engineering application.
Grains of 2# steel are coarse and there is much granular bainite, most of the M/A constituents are long bar-like which worsens impact toughness of material

Influence of Rapid Solidification on the Microstructure and Mechanical Properties of NiAl-Based Near Eutectic Alloys Jianting Guoa, Hutian Lib, Kaiwen Huaic, Gusong Lia Superalloys Division, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China a jtguo@imr.ac.cn, b htli@imr.ac.cn, ckwhuai@imr.ac.cn Keywords: rapid solidification; NiAl-based eutectic alloys; compressive deformation Abstract.
The existence of extensive dislocation network will strengthen the material by providing obstacles for dislocation motion, which could provide a strengthening of the order of [11] f=G∆b/2πb
However, operation of similar sources throughout the material probably leads to the high dislocation density observed throughout the NiAl phase in the samples.

For construction enterprises, zero inventory is to minimize the stock material and construction site materials in construction process as far as possible and to put materials into production immediately, avoiding secondary transfer fee[8] no longer.
Each process should execute strictly with the requirements proposed by next process, including personnel, materials, and machinery equipment.

This science is aimed to improve the work procedure, work techniques, work equipments and match them to mental and physical characteristics of human.
Target group and design criteria regarding to the mantioned materials and the study of domestic and foreign samples of dining table, it is necessary to be considered the following points in design as the premier criteria: using Iranians‘ eating style and custom; solving the ergnomic problems of sitting; using Islam instructions about the most correct ways on eating; making the form of dining table closer to Iranian forms; using the most modern and updated scientific methods in designing, such as modular design; easy pakaging; easy transportation; low weight and using an adequate material which is durable and easy to clean.
Finally the refined data was organized and classified based on the functional, ergonomic and aesthetic states called design criteria as follow: · Smart use of materials and forms in order to clean the table easily; · Contractibility in a small area when it is unused; · Considering the special ceremonies such as Ramadan and time of breaking a fast and dawning; · Changeability of its application from a familial friendly space to a formal party space; · Ease of individuals’ accessability to the things on the table; · Rotatability of table screen; · Assigning some special spaces to place anything (glass, saltshaker, etc.); · It helps to bring meals and take their containers to kitchen after finishing the food; · Being inspired from Iranian art; · Having the sense of comfort during eating; · Reminding the thanksgiving by the form and design of table or tablecloth; · Considering the ergonomic standards of sitting; · Adjustability of its height; · Low weight and easy portability;
The premier criteria, such as the use of Iraninans’ eating style and custom, the resolution of ergonomic sitting problems, the use of Islam instructions about the most correct methods of eating, making the form of furniture closer to Iranian forms, the use of most recent and updated scientific techniques in design like modular design, easy packaging, easy transportaion, low weight and the use of materials which are durable and easy to clean were gathered.
