This is explained by the reduction of carbon content in ferrite due to the enrichment of cementite with Cr leading to the reduction of its equilibrium solubility in ferrite.
It results in a change in mechanical properties (increase in strength and reduction in ductility), which makes difficult the subsequent forming of steel sheet, as it can lead to tearing or cracking of the sheet as well as formation of unsightly stretcher-strain marks on the surface of finished products.
The delay in the start of ageing in Cr steel compared to unalloyed steel is associate with the reduction of C concentration in ferrite due to the enrichment of iron carbides with Cr (by~10%) and formation of alloy carbides, which slows their dissolution on coiling.

The data obtained from the tests were analyzed using SolidWorks software to adjust the material properties to align with the experimental results.
The experimental results revealed that six models exhibited a 133.655% increase in strength and a 7.568% reduction in weight compared to the prototype.
Components designed for applications prioritizing weight reduction: The specimen with an FOS/Mass importance ratio of 30/70 recorded the lowest average weight of 58.208 g.
Compared to the prototype specimen, this resulted in a 7.568% reduction in weight, while maintaining superior strength compared to the reference specimen.

Optimization strategy showed an increase of 83% power reduction compared to previous studies.
In this paper, the CPLD for STTC Viterbi decoder design is considered for the case study of using the power reduction techniques and observing the effect on the system.
Therefore the power reduction techniques will sacrifice for the performance degradation.
Some examples for reducing accesses data is sliding windows [3] and an inverse calculation [6], which reduces power, but again at the expense of increased area and degraded performance.
In table 3, the optimization technique with power consumption data is compared with the previous literature review.

Single-section detection algorithm only detected changes in the traffic data based on a single-section detector to determine whether there is a traffic incident; its representative algorithm is McMaster algorithm.
However, based on the fixed traffic detector AID algorithm performance is largely dependent on the acquisition of fixed traffic detector traffic data quality.
Therefore, how to ease conflicts between the detection performance of the traffic data collection costs and AID algorithm has become one of the key issues to be resolved.
Fixed traffic detector optimized layout principle is based on the AID algorithm detects effect and traffic data collection costs to determine the optimal solution for fixed traffic detector layout.
Automatically based on the multi-source data, road traffic incident detection algorithm of [D].

Web service is an independently developed software specified by its preconditions and effects in the planning context, it can be viewed as a specific process that takes the input data and produces the output data.
we also prescribe “+”, “П1”, “П2”, “П3”, “*” and “×” operations inside the relative vector as follows: k ×bik=bik(k is a positive constant) Definition 5 As for the generated composite service, some concepts may appear in its input and output lists simultaneously (), reduction is defined to adjust its relative vector. the reduction principles are: (1)if and it is an input parameter user required, C1 should be eliminated from the input list of the relative vector; if and it is a output parameter user required, C1 should be eliminated from the output list of the relative vector; otherwise C1 should be eliminated from the output list and the input list of the relative vector.
After reduction, the relative vector of the generated composite service is as + + 。
Definition 6 after reduction a composite service Snew=< Inew,Onew;BCnew,QoSnew >,the matching degree is, where “||” acts element counting .
(6)after reduction, compute the matching degree of each gene., and put it into a feasible callboard

Although the value of m needs more research and data to determine, equation (1) shows that the inter-lamellar spacing is one of the most important parameters affecting yield strength.
This is probably one of the reasons why the data is so scattered and results are contradictory (e.g. at which lamellar spacing the ductility reaches the maxima).
Figure 1 shows the data of the strength vs. reduction-in-area at the fracture of a pearlitic steel with a chemistry of 0.93wt%C-0.82%Mn-1.02wt%Si-0.25wt%V.
The reduction of the lamellar spacing is achieved by cold drawing.
Despite the scattering of the data, one also observes a maximum in reduction-in-area of the fracture.

Sulfide was usually produced during biological sulfate reduction.
Fatty acids can be easily consumed by sulfate reducing bacteria (SRB) for sulfate reduction.
The pH and oxidation-reduction potential (ORP) of liquid samples were measured with a pH/ORP meter (pHS-25).
The DNA of microbial samples in SR-CR process (EGSB reactor) and in A&H-DSR process (EGSB reactor) was extracted for DGGE analysis (data not shown).
For the AN process, microbial community analysis showed the presence of bands corresponding to Nitrobacter sp. and Nitrospina sp. which perform nitrification and convert ammonia to nitrite or nitrate (data not shown) .

In the present study, composites LiFe(PO4)(1-x/3)Fx/C (x=0.00,0.02,0.04,0.06,0.08,0.10) were synthesized by carbothermal reduction method.
In this paper, LiFe(PO4)(1-x/3)Fx/C composites were synthesized by carbothermal reduction method in which formation of conductive carbon and fluorine doping were achieved simultaneously, which greatly improved electrochemical performances of the LiFePO4 materials.
The peak positions were compared with JCPDS data for LiFePO4 (JCPDS file No. 83-2092).
The results show that all obtained XRD patterns are in good agreement with standard data for LiFePO4 with an ordered olivine structure indexed by orthorhombic Pnmb.
