Proportionality limit is the point upto which the stress remains directly proportional to strain whereas elastic limit is the point upto which the material remains elastic ie. if the stress is removed within elastic limit, then the material will regain its original shape and size.

differece between proportional limit and yield point of a spring?
The Law of elasticity states that the strain (deformation) of an elastic object is proportional to the stress applied to it. Since stresses and strains have multiple independent components, the 'proportionality factor' is represented by a linear map (a tensor) constituting a matrix of real numbers.
Within a materials elastic limit, the extension of a uniform section (like a wire) will be proportional to the tensile load. The graph of load (mass) v extension will be a straight line
Within Elastic limit, the strain produced in a body is directly proportional to the stress applied to that body.

The displacement is proportional to the strain. This does not factor for creep and time.
elastic limit
Within the elastic limit of the material, a springs deformation is proportional to its loading.

proportional limit is value of stress that beyond which it is nonlinear; prior to that the stress strain diagram is a straight line. At yield, the material strain will not return to zero after unloading and have a permanent set
The proportional limit is the stress value at which the stress is no longer linear with strain. After that, the material will begin to yield and become non-linear, or plastic, and then it will fail at a higher value called the tensile strength. For most metals, the proportional limit is well below the tensile strength; for example annealed stainless steel has a proportional limit near 30 ksi and tensile strength of 80 ksi; aluminum has a proportional limit of 35 ksi and tensile strength of 42 ksi.
