They found that the multi-pass welding procedure resulted in grain growth at the heat-affected zone (HAZ) and secondary austenite precipitation in the weldment.
The researcher discovered that large ferrite grains become supersaturated with nitrogen in high ferrite concentrations, which can cause the development of Cr2N in the HAZ and WM.
However, they observed Cr precipitation on the grain boundary upon visual inspection.
Therefore, the increase in hardness in WZ of the design point number 9 is attributed to the increase in ferrite volume fraction.
The HAZ of design point number 15 has an austenite volume fraction of 42%, while design point number 4 has a much higher austenite volume fraction of about 56.5%.

With agricultural connotation and denotation having made apparent change, the function of agriculture for producing grain and other commodities is no longer the only function.
With the number of agricultural leisure Sightseeing Park across regions rapidly increasing, the scale continuing to expand, the demand for agriculture leisure sightseeing function presents increasingly vigorous trend.

A great number of polygonal ferrite was recognized.
The proeutectoid ferrite was recognized at the pre-austenite grain boundaries.

Theory It is well-known that continuous distribution of magnetic core ferroparticles on their diameters d is successfully described by lognormal function or Γ distribution and the parameters are determined from the grain size analysis or electro-optical measurements [9].
Additionally, pair correlation functions are the sum over the concentrations of both fractions and over all three types of dipolar coupling constants λ: (4) Indexes pq take the numbers ss, sl, ll.

Introduction A number of both experimental and theoretical studies on explosive welding have been reported[1-12].
The wave length calculated by SPH is 100 µm approximately which is relatively larger than experimental observation in which the interface of metal clad show complicated micro structures between grain boundaries with fusion process.

The grain size of this film is more than 1 µm.
Only a small number of relatively dense regions of the film surface can be observed under the pressure of 100 MPa.

The average grain size of ZnO-TiO3 composite membranes increased with firing temperature increasing.
The mean particle size was determined by counting the number of particle size in a given area of the membrane.

Therefore, numbers of waxy maizes are processed into grain canned or frozen for sale.

By means of powder technology with shaping via cold isostatic pressing a homogeneous microstructure with a medium grain size of approximately 0.4 µm for Zirconia and approximately 0.8 µm for Alumina is generated for the dispersion ceramic (Fig.1).
A number of 15 heads for each of the three neck lengths 28 L, M and S were tested.

Consequently, we may assert that AR ceramics, having a modulus of rupture over 180 MPa (this value was statistically determined on a relatively large number of pieces) can ensure, as a rule, level 4 of ballistic protection.
The size of the directly bound grains, without any vitreous phase, is from 1 to 4 µm.
