What else can I help you with?
When a tensile strength test specimen begins to deform permanently it has reached its?
Tensile yield point or yield strength
What is the yield point of hardened steel?
The yield point of hardened steel is the stress level at which the material begins to deform plastically, meaning it will not return to its original shape once the stress is removed. This point varies depending on the specific alloy and heat treatment of the steel, but generally, hardened steels can have yield strengths ranging from about 500 to over 2,000 MPa (megapascals). Beyond this yield point, any additional stress can lead to permanent deformation or failure. Understanding the yield point is crucial for applications where steel components are subject to high loads or impacts.
Why Aluminium has no lower yield point like Mild Steel?
Aluminium does not have a distinct lower yield point like mild steel due to its face-centered cubic (FCC) crystal structure, which allows for more uniform plastic deformation. In mild steel, the body-centered cubic (BCC) structure results in a noticeable yield point due to the movement of dislocations being more restricted. As a result, aluminium exhibits a more gradual transition from elastic to plastic deformation, lacking a clear demarcation between yield and non-yield behavior. This characteristic makes aluminium behave differently under stress compared to mild steel.
When ultimate tensile strength will be equals to yield strength?
Ultimate tensile strength (UTS) equals yield strength in materials that exhibit a very limited plastic deformation before fracture, typically in brittle materials. In such cases, the material fails shortly after reaching its yield point without undergoing significant elongation or necking. This scenario is often observed in ceramics or some hard metals, where the distinction between yield and ultimate tensile strength becomes negligible due to the lack of ductility.
Why does the theoretical yield differ from the actual yield?
The theoretical yield is the amount of product that we predict will be obtained, calculated from the eqquation. The actual yield is the amount of product that is actually obtained at the end of the procedure.
Why the mild steel have two yield points?
Low carbon steels suffer from yield-point runout where the material has two yield points. The first yield point (or upper yield point) is higher than the second and the yield drops dramatically after the upper yield point. If a low carbon steel is only stressed to some point between the upper and lower yield point then the surface may develop Lüder bands.
What is the difference of rupture point and yield point?

What is the dividend yield considered to be?
The dividend yield is considered to be the most important aspect of any yield. It is the point at which a yield becomes profitable and remains profitable after that.
When does the yield strength of a rectangular metal wire say stainless steel or titanium wire increase?
If you work it beyond the yield point then you raise the yield point in a process called strain hardening
A test specimen is stressed beyond the yield point and is then unloaded its yield point will be?
increased...because the specimen is strain hardened due to plastic deformation.
What is the difference the proportional limit and the yield point of a spring that has been over stretched?
The proportional limit is the maximum stress at which stress and strain are directly proportional. The yield point is the stress at which the material begins to deform plastically. If a spring has been overstretched beyond its yield point, it won't return to its original shape when the load is removed.
When a tensile strength test specimen begins to deform permanently it has reached its?
Tensile yield point or yield strength

What is mean by yield strength of steel?
The steel has a ductile material properties so that it could be elongate at a point of ultimate yield point.It is stable while before the break point
Referring to changes in yields a basis point equals?
A basis point represents a one-hundredth of a percentage point change. For example, if a bond yield increases by 25 basis points, it means that the yield has increased by 0.25%.
What factors affect the melting point of aspirin?
losing yield
How do you calculate production yields?
Total yield in a unit in a unit input. Graphically the production yield can be plotted against the unit input to determine the production yield at any point.
