Taking into account the chemical composition of maraging steel 1.2799, the data found in the literature [1- 3, 9, 10], and the average microhardness measured, i.e. 599 HV0.1 (≈ 53 HRC), it may be inferred that the microstructure shown in the figure is martensite, including precipitated precipitates of Ni3Mo in Ni3Ti, which have a decisive influence on maraging steel hardening. 342 HV0.1 (≈ 35 HRC) 599 HV0.1 (≈ 53 HRC) 561 HV0.1 (≈ 51 HRC).
Then follows first rather steep and then gradual through-depth reduction of stresses.

It has been found that, joints with no defects were obtained in a wide range of welding speeds and the existence of the non-rotational shoulder completely eliminates the thickness reduction phenomenon.
It has been found that, computed results should have good agreement with experimental counterpart because of limited data available in open literature to predict variation in material hardness throughout the various FSW zones of two alloy.

The monthly mean temperature(shows in Figure 3), wind speed and direction,cloud amount,humidity,and the net solar radiation day and night (Calculated according to 8 hours of sunshine ) are calculated according to reference value for each region, and the part of the relevant dates could be obtained from China meteorological data Sharing Service System.
Due to the presence of ice, the solar radiation acting on the water will be in a significant reduction, the function of the surface wind will be hindered, and the heat exchange between surface of the water and the atmosphere will be almost stopped.

Because of the lack of data on {112} slip systems, only the interactions between the dislocations belonging to the same slip system, i.e. α = u, and different slip systems, i.e. α ̸= u, will be distinguished for Aαu.
In this example, a reduction in the yield strength of the material is observed after a load reversal.

According to the industrial production heat treatment process parameters of Al-Mg-Si automotive alloy sheet, the hot-rolled sheet was cold rolled to 80% reduction in thickness and subjected to a solution heat treatment at 560°C for 5 min in an air-circulated furnace and the quenched into water.
Five data points were carried out to ensure the accuracy of the results.
